Just got a gy6 and started to get it running again. It fires right up but runs super rough, revs kind of go up and down holding the throttle open. I posted a video to make it a bit clearer. I figure it was fuel related, it has a new carburetor. Runs the same as the old. I though it must be a timing issue, but the timing, and stator look perfect. Has good spark. My only other thoughts are maybe something wrong with the valves?? The gaps are good. Any ideas?
